Why would a guy kneel down right behind me when he has to tie his shoes?

He does this nearly every morning when he comes in and occasionally in the afternoons as well. Always kneeling down right behind me.. like a foot away at most and facing my direction. Our work stations are next to each other but we have ample open space around us to spread out in. It feels intentional but this person also comes across so kind and polite I can’t figure it out.
